1. The advantages of cash are: it can be used at will and has strong liquidity. It can be used immediately to purchase goods, goods, services or repay debts, and can meet expenditure needs in a timely manner;

Disadvantages of cash: high risk, inconvenient to carry.

2. Advantages of checks:

1. Safety. Solve the spatial obstacles of cash payment between the two places;

2. Credit function. The use of bills can solve the time barrier of cash payment. The bill itself is not a commodity, it is a written payment voucher based on credit;

3. Payment function. The use of bills can solve the hassle of cash payment procedures. Bills can be transferred multiple times through endorsement and become a circulation and payment tool in the market, reducing the use of cash.

Disadvantages of checks:

1. Time limit, banks will not accept overdue payment;

2. Checks can only be used in the same city;

3. The procedure is complicated and there must be three basic parties: drawer, payer and payee.

3. Advantages of credit cards

1. Suitable for frequent business trips and inconvenient withdrawals from other places. Therefore, credit cards are often used, including electronic tickets, hotels, and restaurants, and the pressure on borrowing money is much less.

2. Installment payment for bulk purchases. I basically use credit cards to pay for home appliances, mobile phones, and laptops

3. For business trips and banquets, use credit cards to associate with some specific merchants, restaurants, and flight booking (such as Ctrip, airlines) cards , there are points discounts (of course the gifts are all personal gifts, haha)

4. Spend in advance and pay in installments. When I see something I like and clothes, shoes and bags that my wife likes, I buy it immediately. 50 days of interest can add up to a lot. For well-off families that are just starting out, it is recommended not to swipe their cards too many times, otherwise they will not be able to see their actual cash flow expenditures.

5. Spend by credit card online. This is not recommended, but some websites are really convenient. It can also be associated, but it must be protected by a password.

6. Withdraw cash from other places. A poor family's road to wealth. It's hard to have no money in a different place. You can withdraw some cash in advance, but of course there will be a handling fee.

As for the disadvantages, it all depends on your ability to repay your purchases. It is best not to be blacklisted and create a bad record for your credit. There is also the matter of one’s own consumption control.
